In the APS infrastructure, its backend contains the following interacting components and interfaces between them.
APS controller (APSC) is the central part that is responsible for the following operations:
Control the central storage of all APS resources, types, and packages.
Manage the interaction between all other components in the APS infrastructure. This messaging functionality is often referred to as a service bus. Its own base endpoint is https://apsc/aps/2/, where apsc must be changed to the actual domain name of the management node. The short /aps/2/ base URL will be used in almost all examples to represent the APS controller base endpoint.
When managing APS objects, all communications must go through the APS controller.
Each integrated application is represented by its APS application, which contains two active integration components:
APS user interface represents the one-way communication tool connecting users with other components through the APS controller.
